Abstract

En fremgangsmåte og en anordning (13) er beskrevet for elektrolytisk beising av flate metallprodukter (2), spesielt spesialstål- og/eller karbonstålstrimler. Minst en diamantelektrode og/eller minst en bly/tinnelektrode, for eksempel en bly93/tinn7-elektrode (15) blir benyttet. De spesielle egenskaper hos diamantelektrodene og/eller bly/tinn-elektrodene er i form av vannspalting. Mens vann vanligvis, ved elektrolyse, blir spaltet til hydrogen og oksygen, tilveiebringer diamantelektroden og/eller bly/tinnelektroden et arbeidsspekter i hvilket ozon eller svært reaktive hydroksylradikaler blir dannet i stedet for oksygen. Som et resultat blir beisingstidene vesentlig redusert sammenlignet med konvensjonell kjemisk beising, og også sammenlignet med konvensjonell elektrolytisk beising.A method and apparatus (13) are described for electrolytic pickling of flat metal products (2), in particular special steel and / or carbon steel strips. At least one diamond electrode and / or at least one lead / tin electrode, for example, a lead93 / tin7 electrode (15) are used. The special properties of the diamond electrodes and / or lead / tin electrodes are in the form of water splitting. While water is usually, by electrolysis, decomposed into hydrogen and oxygen, the diamond electrode and / or lead / tin electrode provide a working spectrum in which ozone or highly reactive hydroxyl radicals are formed instead of oxygen. As a result, pickling times are significantly reduced compared to conventional chemical pickling, and also compared to conventional electrolytic pickling.
